1st sorry for the long post and I hope it is the right place.

I was setting at a light this morning with the radio up and was waiting to turn when the light turned my TY was not running so I put it park to start it again and it started and ran for about 2-3 sec. And cut back off. So I restart like 3-4 times and would not stay running so I got it running and put it in gear and one foot on the break and one on the gas to keep it running. Pulled into the fire department where I work and it didn’t cut off any more but ran just a little ruff. No trouble codes? Went out tonight and started it and let it warm up and it ran fine. Any ideas would be great!

If it will run ok with some throttle but quits with your foot off the throttle I'd suspect the IAC and/or the TPS.

Can DM show if IAC or TPS is not working right?

"working right" and what their data is are two different things I would think but it will give you a good idea. From the DM help file:

IAC Position
This is the actual counts (0 to 255) for the Idle Air Control Valve position. This valve controls the idle speed and air density during throttle overrun conditions.
TPS Volts
This shows the voltage measured from the Throttle Position Sensor. Will generally range from 0.5 Volts (throttle closed) to 4.5 Volts (throttle fully open).
